Abstract
The results of the Mossbauer spectroscopy investigations of amorphous magnetic Fe-57/C films, produced by the pulse-laser deposition and mag netron sputtering are presented. The Mossbauer electron conversion spe ctroscopy method is shown to provide an opportunity for spectral line broadening up to 63 Gamma(o), and for controlling the filter width by varying the iron concentration in amorphous films at sputtering. The m anipulation by the width of nuclear-resonant spectra is also possible by varying the temperature near Curie point. Another way of further br oadening the Mossbauer spectra by means of multilayer interference str uctures containing a resonant isotope are discussed.
